Check the pic, on rear frame, right side, above and to the left of the 2004, there is little box shaped casting...what is it for? kickstart stop? the reason I ask is mine appears to be relocated slightly.

That is what I believed it to be...mine has been broken off, turned 180 degrees (according to broken surfaces) and welded on a half-inch outboard. I assumed thatthis was done with wheels/tires/chain intact in racing environment, easier to relocate it there.

Without knowing for sure what its intended purppose was, I couldn't tell if it was a race mod or half-fast repair.
